Concrete Bond Strength, Anchor and Pull-off Testers

Bond Strength

Adequate direct tensile strength or bonding strength between two layers is important if repairs to concrete structures or additional overlays and screeding on existing concrete is to be structurally sound. more »

Bond Strength, continued

The pull-off test as a means of projecting the compressive strength of concrete and other materials involves bonding a circular steel disc to the surface by means of an epoxy resin adhesive. A controlled tensile force is then applied to the disc, and as the strength of the bond is greater than that of the material under stress it will eventually fail in tension. From the area of the disc and the force applied at failure it is possible to calculate a nominal tensile strength for the material.

Humboldt offers an array of bond testers, pull-off testers and anchor testers from several manufacturers of testing equipment used for bond testing. If you have questions or need help selecting equipment, please call us at 1.800.544.7220 or use our Quick Response form.
